The United States agreed to engage in a "Europe First Strategy" with Great Britain because its priority was to help its allies first defeat the Nazis. Following the Nazis successful invasion of France the United States sought to prevent the Nazis from invading Great Britain and instead defeat them first.
This major American right that people living in the United States outlying areas (or U.S. Territories) do not have is the right to vote for president. People born in Guam, Puerto Rico, or the Minor Outlying Areas, for instance, are Americans or US citizens, and they vote in the congressional elections and in the presidential primaries, but they can't vote for president unless they move to one of the states or to the District of Columbia (the mainland). The United States Electoral College does not provide for them to vote.
